Hello all,
i have an Problem:
We have retrofited an Maho MH600W with an DSPMC, an Pokey57E with an PoNetKBD48 and the old Indramat drives!
The Machine works fine when i use the Automatic, MDI and jog over the PC Keyboard!
When i use the Stepmode in Mach3 and i like to jog for exampe the x-Axis over the Pokey KBD48 then all axes will move! When the error is big enough then the axes will goe uncontrolled thrue! :-\
When i use the normal Jog mode and do the same over the PC Keyboard i can work without Problems!
I told this issue Mr. Matevž Bošnak from POLABS he have checket all on his side and it looks good!
So i have no idea what´s happent on the DSPMC side!
I remember an Topic from here but no Answer
http://www.machsupport.com/forum/index.php/topic,25789.msg181690.html#msg181690
I asket him how it is with all axises on his Machine but it looks the same! All axes will move at the same time just without the PoNetKBD48!
Has anybody an idea what´s happend?
Thanks for your Answer!

In step jog mode, mach3 generates the commanded motion, and dspmc just make sure all axis follow the position stream from mach. can you send the debug log text from the black dos window, so we can try to analyze what may be happening.
thanks

I'm having the same problem. I'm using the DSPMC to retrofit an Accurite Millpwr. It works great except for this issue.
I don't have Pokey. I have a PC connected to the DSPMC, which is driving a Servo Dynamics 1525 servo amp.
In step mode, pressing any of the arrow keys will move all three axis the same direction the same amount. It doesn't matter which key I press, they all move the same direction.

pls send your mach3 xml profile to support at vitalsystem dot com. will try to replicate and solve the issue.

Hello,
thanks for your Answer!
I have send you an e-mail with the xml file so you can try to replicate!
I hope you will find out the reason for this issue.
When you like to get an error log tell me!
Cause the machine stay on an company and i can only do this over an remote conection.
When you wrote about an DOS window please descripe it how i have to use your loging mecanism because i havn´t used before!
One monre question:
I read in other topics about to connect an MPG too!
So why it is so important to connect the MPG directly over hard/soft encoder on the DSPMC?
You wrote that mach3 generates the commanded motion and the DSPMC wil follow the position stream!
Why i ask:
I work normaly with Siemens 804D Solution Line Controlls and SINAMICS Drives!
They use an Machine Conroll Pannel too ant the MPC is for Example only an part of the Controll not more (Without look up for Safety) ;D
So this is the reason wy i like to use the Pokey and the KBD48CNC and in future an MPG over Pokey.
This way is an very comfortable way to keep the outlay of wiring small.

Hello,
We made a plugin fix that can be downloaded from here:
http://www.vitalsystem.com/portal/motion/dspmc/DSPMC_StepGen.zip
NOTE: If upgrading from a version 7 or older firmware, please go over the "readme.txt" in the zip folder.
Aside from the plugin fix, the pid tuning for the axes must be tightened. This can be done in the Axis config tab in the Mach3 DSPMC plugin. Please use the graph as a guide.

Hope this helps,

Hello Marc,
thanks for your Answer!
In will try out tihs!
but it will take a wile cause i dont like to this Softwareupdate over an remote connection! :D
I give you an request if it will work!

Hello eurohoppel,
The MPG is connected directly to the Encoder Input Channels on the DSPMC because MPG and jog motion are performed inside the controller. Mach only issues commands to start the jog motion and displays feedback data. Having the jog motion and MPG motion generated inside the DSPMC improves the performance significantly and makes the motion more precise and responsive.
It is still possible to use a USB MPG with the DSPMC. You would just need to go to the System tab of the plugin config then look for a checkbox labelled as "Enable USB MPG". While checked, this option will disable the our MPG logic and prevent it from overriding the USB MPG plugin.

Hello Marc,
thanks for your Answer!
Perfect!
It will help me for a lot! :)
I will try it out soon as posible and give you an request for this also.

Hello Ray,
Yes, the USB MPG update to the DSPMC plugin was applied not that far in the past. So a firmware and plugin update should allow you to use a USB MPG plugin.
Again, please follow the "readme.txt" in the DSPMC files zip folder because there is a small chance that you could brick your unit while improperly upgrading the FPGA.

Marc,
I loaded the new code and now my mill is immediately resetting. The notes say I may have to change some I/O settings if the unit was on an older release. Is there a table that says what the changes are so I don't have to guess what needs fixing?
Thank you,

I got it working. I had to reverse the e-stop polarity. Now the step function works on both the pendant and the keyboard. But now the jog does not work on the pendant. Jog works on the keyboard. I'll have to chew on that a bit. I can't think of what would cause that.
-
I can't find "enable USB MPG check box" how do I know if I have the latest firmware or plugin update, I think Feb, was the latest I did.
Ray.

Hello i´m back with News!
I have Installed the new Update and it will work fine with Pokey57E and the KBD48CNC!
The Inputs are still changed active low / high and the Drives must be reconfigured but in my case it is now better than before!
For example when we cut out an Bolt out form Aluminium we are in tolerances in 0.002mm in all axes and all will be happy!
Thank´s for your Help! :)
Next step in a view of weeks is how it will work with an MPG beause my Customer like one for future!
We will setup this over the Pokey and i think it will work too!
When not you will read about but i don´t think so! ;D
Best Regards
Uwe

@ Dresda,
please look for the Softwareupdate on the Firstpage and you will find the right one on this Link http://www.vitalsystem.com/portal/motion/dspmc/DSPMC_StepGen.zip (http://www.vitalsystem.com/portal/motion/dspmc/DSPMC_StepGen.zip)
For the USB enable Checkbox look at the picture!
Good luck! ;)

This load fixed one thing and broke another. I can now step with the jog function on my pendant. But now the continuous jog mode does not work.
I have the Russian pendant that has a step wheel and jog wheel. The jog wheel worked in the previous load, but now it does not work. Mach 3 reports 'Already in Jogging Mode!!"
Can you have another look at the code to see what might be the issue?
-
I have just about given up with the whole thing and I have been servicing CNC machines for over 40 years, but not PC based, if you use the motion board in between you will have nothing but trouble, first you get one thing to work then another doesn't.

Hello Pofo,
If you're using a USB MPG (or any kind of MPG that connects on the PC and not the DSPMC), then you have to check the "Enable Mach3 USB MPG" setting in the System Tab of the plugin config. This simply overrides the DSPMC plugin's MPG logic to make room for your MPG plugin.
The message "Already in Jogging Mode!!" is printed because you didn't check the "Enable Mach3 USB MPG" setting.

Marc,
Thank you. That fixed it. All is well.
My appologies for blaming the software update.
